You may want to spend a few dollars/euros on a variable 0-10K resistor and change it until it works consistently. If the long wiring is acting like a resistor you may have to lower the resistance but as Sailoog says you may have to increase the resistance. You could trim until it works, then measure the resistance of the variable resistor and find a fixed value resistor to replace it. With mine, rather than adding a second 4.7K resistor inline, I removed the existing 4.7K from next to the LED and replaced it with a 10K - cleaner install
